The Annotated Hobbit by J.R.R. Tolkien

As I reread this book, I didn't spend as much time as I have in the past on the annotations. I liked the way the bits of older material (such as Gondolin) kept popping up. I also appreciated the way that Bilbo finds himself, through Gandalf's work and his own good sense and good luck, a leader among the dwarfs. Finally, this time I noticed echoes of the Lord of the Rings: especially in the involvement of the eagles.
